SolidGoldFX Supa Funk

The SolidGoldFX Supa Funk, launched in October 2021 as the Supa Funk Envelope Bi-Filter, is a compact envelope filter pedal with an all-analog audio path and two blendable low-pass filters¹². An envelope filter, sometimes called an auto-wah, listens to how hard you pick and opens and closes a filter in response, so your playing dynamics shape the sweep. Where a single-filter design gives you one quack, the Supa Funk's second low-pass filter, blended in with the Color knob, lets you move from what SolidGoldFX calls "classic bom-chicka-wow-wow funk, all the way to rich, throaty and vocal filter sweeps"¹.

SolidGoldFX makes the Supa Funk, an envelope filter pedal with an all analog audio path and parameters to fine tune the envelope response, built in Montreal, Canada¹. The maker describes it as a distillation of its earlier filter devices, the Funkzilla and Funk Lite¹.

What it does to your sound

The core of the pedal is a tuneable analog envelope generator driving two low-pass filters¹. The envelope generator reads your attack and translates it into a filter sweep, and its depth, frequency and sensitivity controls let you tune how the filter reacts to your touch¹. The second low-pass filter is the "bi-filter" part: blending it in with the Color knob thickens the effect and pushes it toward those throaty, vocal sweeps¹³.

There is also a fixed filter mode. MusicRadar's Jonathan Horsley noted that turning the Sensitivity knob fully counterclockwise switches off the envelope, letting you use the pedal as a fixed filter for cocked-wah sounds or lo-fi textures⁴. That gives the Supa Funk a second life as a set-and-forget tone shaper rather than a dynamic one.

Gearnews' reviewer Jef summed up the sound:

The controls

The pedal has five knobs and a single toggle¹. SolidGoldFX says these let you determine whether you are slinging out subtle low-pass sweeps or shooting for more extreme filter effects, with parameters to fine tune envelope response, filter center and response, output level and filter direction¹.

The Direction switch is the personality toggle. MusicRadar described the reverse setting as "a little more of a sci-fi, weird feel" compared with the traditional forward sweep⁴. Between the reverse direction, the fixed filter mode and the Color blend, the pedal covers a wide range of filter territory from one small box.

Power, bypass and board placement

The Supa Funk runs on a regular 9V DC center-negative power supply and draws 20 mA¹. MusicRadar's coverage put the draw at under 20 mA⁴. There is no mention of battery operation in the maker's specifications, so plan on a pedalboard power supply. True bypass switching means the pedal stays out of your signal chain when off, and the top-mounted input and output jacks keep the footprint tight against its neighbors on a board¹². The enclosure is finished with a 70's wallpaper print¹.

Guitar, bass, synth and more

The Supa Funk is not guitar-only. SolidGoldFX says it is suitable for guitar, bass, synth and keys, and other electronic applications¹. MusicRadar's launch coverage echoed this, noting the maker says it will happily process signals from your synthesizer, electronic keyboard, bass guitar and other electronic signals as well as electric guitar⁴. Because the envelope generator responds to input level, players of lower-output instruments may simply need to raise the Sensitivity control to get the filter moving.

From Funkzilla and Funk Lite to Supa Funk

The Supa Funk did not appear from nowhere. SolidGoldFX describes it as a distillation of the maker's previous filter devices, the Funkzilla and Funk Lite¹. Guitar World's coverage framed it the same way: building on the brand's previous Funkzilla and Funk Lite, the compact Supa Funk features blendable low-pass filters². Gearnews also noted it follows on from the Funkzilla and Funk Lite pedals³.

The Supa Funk follows on from two earlier SolidGoldFX filter pedals, the Funkzilla and the Funk Lite¹³. The maker describes the new pedal as a distillation of those previous filter devices¹, and press coverage notes that the compact Supa Funk builds on the brand's previous Funkzilla and Funk Lite with blendable low pass filters¹².

SolidGoldFX is also known for its fuzz pedals, including the Imperial MkII Fuzz, as covered by Pedal of the Day⁶, so the Supa Funk sits in a catalog that spans both filter and fuzz territory.
